Abstract

An LBD vehicle lamp, which essentially comprises a lamp holder, at least one LBD and a lampshade, characterized in that: the lampshade is barrel-shaped, and a hollow groove is opened inside the lampshade from the inner end face to the interior of the barrel; the hollow groove can hold the LBD and wall of the groove can wrap the LBD; a sunken groove is formed on the outer end face of the lampshade; with help of the dense wrapping of the LBD by the lampshade, a lens effect that enables light diffusion and expands the astigmatism of the shiny side is realized. The utility model also forms a relative sectional difference in the rear section of the lampshade barrel, and a reflecting layer is formed on the outer margin of the sectional difference. The reflecting layer can restrict the transmission of light, enabling the LBD light beams to concentrate and shoot out from the front end face.

Description

The led vehicle light fixture

The utility model relates to a kind of vehicle lamp, refers to the car light of light emitting diode especially.

Vehicle lamp provides security warning and the usefulness of finding out road conditions.General vehicle light fixture more than 1 uses traditional osram lamp 11 light sources (as shown in Figure 7) now, yet the easy high temperature of this type of conventional bulb burns Ruined, shake is disconnected and light is dazzling.Develop not only with scientific and technological progress and light emitting diode 21 (but also claiming the LED lamp) (as shown in Figure 8), because the light source of light emitting diode is with the radiation kenel, light is gentle and be difficult for advantages such as shake is disconnected, is used gradually.Yet the light source of light emitting diode is owing to light irradiation kenel is shone with boundling light, comparatively narrow for the floodlight effect (halation) around the bulb, make the driver that sends a car feel too small, therefore the light emitting diode end face is made a recessed groove 211 for the area of experiencing of light; Make light see through recessed groove (concavees lens) and form the light diffusion, enlarge the astigmat effect of light face.The light that right this kind design produces still may be lost and in disorder by the lampshade peripheral part.

The purpose of this utility model is, improves the deficiency that above-mentioned design exists, and a kind of new vehicle lamp design is provided, and the light of light emitting diode is effectively spread, and makes the driver that sends a car experience the area appropriateness and the intensified safety effect for light.

The purpose of this utility model is to realize like this, light-emitting diode (LED) car lamp, mainly comprise a lamp socket, at least one light emitting diode and a lampshade, this lampshade is a tubular, the lampshade inner side end is offered a hollow groove in tube, this hollow groove just can ccontaining light emitting diode, and forms and coat, and lampshade outside end face forms a recessed groove, can make the light diffusion, enlarge the astigmat effect of light face; The lampshade front end is inboard corresponding to recessed groove projecting inward, can make the earlier preliminary optically focused of light of several light emitting diodes; Lampshade cylindrical shell back segment forms one, and section is poor relatively, and outer rim is nested with a ring set, and the ring set internal layer has a reflector layer, and the transmission of reflector layer restriction light makes light concentrate on the lampshade front end face and penetrates.

The ring set internal layer is preferably the rete of minute surface or coating low light transmission.

The recessed groove surface in the lampshade outside is set as atomizing face or circular fringes.

The utlity model has following effect:

1, the unique design of lampshade can change the phenomenon of light boundling, highlights the light source of LED light lamp, produces dispersion effect for the light around the bulb, makes the driver that sends a car bigger for photosurface.

2, this creation is offered a hollow groove 331 by lampshade inside by inner side end in tube, and this hollow groove 331 just can be installed with light emitting diode 32, forms careful and compound coating, and protective is preferable.

3, this lampshade hollow groove forms the cell wall of a light filtration, for light one preliminary integration is arranged.

4, this creation lampshade front end face forms a recessed groove 332, and light forms the effect of scattering via concavees lens.Form bigger light face.

5, another advantage that this creation is derived is that the lampshade front end face is a recessed groove 332, can improve the intensity that the lampshade front end face bears bump, and arranged the service life of length.

6, in addition, this creation lampshade front inner wall forms an inward flange 333 with respect to recessed groove; When installing several bulbs so as to making, can be earlier to the preliminary optically focused of light.

7, the transmission of this reflector layer restriction light is borrowed in this creation, makes light that the one preferable effect that concentrates on the front end face ejaculation is arranged.

Accompanying drawing provides embodiment of the present utility model.

Below in conjunction with accompanying drawing the utility model is elaborated:

See also Fig. 2, cooperate shown in Figure 1ly, this creation is a kind of light-emitting diode (LED) car lamp 3, mainly comprises:

One lamp socket 31, number light emitting diode 32, a lampshade 33; Wherein,

This lampshade 33 generally is a tubular, and lampshade outside end face forms a recessed groove 332, and this recessed groove can form the atomizing face that manifests in graphic as Fig. 1,2,3 etc. in the surface.Also can shown in Fig. 4,5, form circular fringes.

This lampshade inner side end is offered dead slot 331 among the sub-tubular in tube; This hollow groove one end face opening just can be installed with light-emittingdiode pipe 32 and insert, and makes the cell wall of hollow groove 331 that light emitting diode is formed coating.

These lampshade hollow groove 331 inboard end walls with respect to recessed groove 332, and form an inward flange 333.

This lampshade cylindrical shell back segment forms one, and section is poor relatively, and this section difference outer rim has a ring set 334, and a reflector layer is arranged on the ring set.Reflector layer is preferred embodiment with the ring set 334 that inner edge has minute surface.

In addition, see also Fig. 3, this reflector layer also can be a kind of reflexed light film 335 of coating reflectorized material, and has effect same.

See also shown in Figure 6, this creation hollow groove 331 inboard end walls, corresponding with recessed groove 332 and form inward flange 333; When loading onto several light emitting diodes 32, can begin to take shape a spotlight effect (optically focused of convex lens) earlier to these several light emitting diodes.And cooperate the transmission of this creation lampshade 33 cylindrical shell back segment reflector layers 335 restriction light, make light that the one preferable effect that concentrates on the front end face ejaculation is arranged.

Behind the light constriction, light is penetrated by the protruding inward flange 333 of lampshade front end; Make the light diffusion via recessed groove 332, reach the astigmat effect that enlarges the light face.

Because the light source of light emitting diode is with the radiation kenel, light is gentle and shine with boundling light, comparatively narrow for the floodlight effect (halation) around the bulb, and adopting the light fixture of this creation, light can form the effect of scattering via concavees lens, therefore, the astigmatic effect of this creation can external structure correction light boundling, and when making light through this creation lampshade front end face (interface), light scatters.

Above-mentioned institute is old to be a preferred embodiment on this creation industry, and the equalization of being done according to this creation claim changes such as, all belongs to the row of this case claim.
